Latching Relay G2AK CSM G2AK DS E 2 1 Magnetic Latching Version of G2A Ideal for Sequence Control Double-winding latch system with continuous rating. Terminals pulled from the respective junctions between the built-in diodes and set and reset coils allow the built-in diodes to be externally connected for coil surge absorption. Excellent vibration/shock resistance with minimal secular decrease in latching power. Easy monitoring of ON/OFF operation due to the built-in operation indicator mechanism. Same outline dimensions as the standard models of G2A.

The rated current and coil resistance are measured at a coil temperature of 23C with tolerances of +15%, 20% for AC rated current and 15% for DC coil resistance. 2. The AC coil resistance values are for reference only. 3. Performance characteristics data are measured at a coil temperature of 23C. 4. The rated current of the AC operating coil is half-wave rectified current and is measured with a DC ammeter. 5. The peak reverse-breakdown voltage of the built-in diode is 1,000V. 6. The set coil of the Relay rated at 6 VDC is of the 5-minute rating. However, when it is used by connecting a diode is series, it can be of the continuous rating. 7. By connecting an external resistor to each of the set and reset coils as shown in the table below, the rated current of the Relay can be increased. 8. The maximum voltage is one that is applicable instantaneously to the Relay coil at 23C and not continuously.
